Try not using conditioners of any kind. I was getting some really thin places on my head, very embarrassing. I only condition once a week now.
Also, I was taking Prem-Pro. I also went off the hormones. My hair's so thick now, my hairdresser has to thin it.
Hope this helps.
By the way, I 'let my hair go' and my hair is the most beautiful white you've ever seen! Stunning! I use Loreal Mega Lightest Ivory Blonde
to keep the yellow tinge out about every 2 months or so,and use Shimmer Lights shampoo daily to keep it snow white.
Stunning!
